Forgot to say your leg pain does sound like sciatica but only if it travels down the back of the leg following the path of the nerve.
Hi there,
Well the most telling thing from your scan is . . . . No evidence of a significant disc protrusion into the spinal canal. . . . so sciatica (or other nerve pain) should not be a problem as sciatica is the impingement of the sciatic nerve at some point along it's length. That is where the problem lies . . . spinal and neuro surgeons only recognise disc or spine related nerve impingment when it relates to sciatic nerve impingment. BUT this nerve is the longest in the body, so it makes sense( to everyone except neuro surgeons) that there could be a problem lower down the nerves length. Check out piriformis syndrome.(PS) You tube Dr's Aaron Filler and George Best and google PS.
See if any of your symptoms relate. It is rare so maybe not, but worth a look.
For treatment try conservative exercise, pilates,physio, etc. Nothing on your scan would indicate a need for surgery and any way even if it did always try conservative measures 1st. There is a PS stretching exercise on You Tube if you think it may be that. What did the consultant say about your scan?
Take care.
